Description

200426783 (1) Description of the invention: [Technical field to which the invention belongs] The present invention generally relates to copy protection of optical storage media. More specifically, the present invention is directed to a system and method for using fuzzy bits for copy protection of optical, magneto-optical, and hybrid storage media. [Previous Technology] Optical, magneto-optical, and hybrid storage media such as compact discs (CDs) and digital video disks (Dvds) currently require inexpensive, reliable media that can store large amounts of digital content for the consumer. As used herein, optical, magneto-optical and hybrid storage media, and other examples of formats in which the desired format is all digital storage media. The aforementioned digital storage media can be used to store a variety of digital content, including digital music, video, computer software, and other data. There are numerous media players for reading digital content from the aforementioned digital storage media, including CD players, DVD players, CD-ROM players, and game consoles such as Sony's Playstation 2TM from Microsoft Corporation. As used herein, the foregoing are all considered media players. Note that this is not an exhaustive list of media players and that other media players can be used. In particular, optical storage media such as CDs and DVDs are produced through a thermal post-processability process. Injection molding is a thermal post processability paradigm for generating optical storage media. The digital content on the optical storage medium is a series of data bits represented by grooves and land, and the grooves and land are converted into a binary data stream represented by 0 and 1 by an optical media player. In the method of producing optical storage media, the pre-dominated digital content is optically recorded on a mother surface made of glass or a photoresist-coated substrate 87819 200426783. A recorder is produced from a mother body by depositing a metal (e.g., nickel) layer onto the mother body by using an electroforming process. The recorder is then used in the reproduction process to hot-mould a transparent disc (which will become an optical storage medium. As long as it is hot-moulded, the transparent disc can be made by using what is known as metallization-reflection: genus (such as aluminum, gold, etc.) Coatings. CDs such as CDs are then coated with a protective varnish to protect the reflective metal surface. This represents the finished optical storage media. Other optical storage media such as DVDs are optical discs that can pass through three layers of DVD: layer center-adhesive It is protected. By using the ^ screen ^ printing processes and methods known in the technology, the non-recorded surface of the optical storage medium can display drawing, fine art or other printed information as needed. The aforementioned digital storage media has been lost due to theft of stored digital content. Countless technical solutions have been proposed, and many implementations have protected digital content from duplication or unauthorized reproduction. For example, Microsoft Corporation has used expensive optical storage media Edge-to-edge

Edge) and Inner-hub_dng hologram nest storage media signature. In addition, the certification system proposes to cite errors, ambiguous symbols, and patterns on storage media that use land and grooves to encode the storage media. These errors, ambiguous symbols, and patterns can be confirmed to authenticate the storage medium. However, 'to now' there are no implementable technologies that cannot be compromised by conscientious computer programmers. Therefore, in a technical aspect of the system and method, there is a need for a system and method capable of providing copy protection for optical, magneto-optical, and hybrid digital storage media. [Summary of the Invention] According to a specific embodiment of the present invention, the storage medium provided can be broadcasted by a broadcaster 87619 200426783 yuan 0 Still according to another specific benefit ~ Through other examples, a program storage device is provided to implement the implementation by a machine. left foot, so the ceremony program, to execute a certification methodology for program storage device, the dragon.

According to the -step-by-step specific embodiment, a program storage device is provided to substantially implement the instructions executed by the -machine Program to execute a method for authenticating a program storage device, where the storage device can store a digital read by a machine, the method includes: reading the program storage several times A series of bits at a predetermined position of the storage device; comparing a plurality of read bit strings from the predetermined position to determine whether the bits in bit_ are substantially the same for each read; and if The bits in the bit string are substantially the same, so that the machine stops reading the digital content stored on the program storage device. [Embodiment] FIG. 1 illustrates a conventional media player (such as CD / DVD media) according to the present invention. Player) Read example 100 obtained from a digital storage medium (eg, optical storage medium). Reference numeral 102 indicates a number of samples taken by the media player along a magnetic track 104 of the optical storage medium. For example, η11Τπ describes the eleven samples taken by the multimedia player along the magnetic track 104 of the optical storage medium during the conversation 103. As described in the special description of the example 10087, 878-19-11-200426783, for example, the sample "3T" and others Sampling is available, which represents the three samples taken by the media player during the conversation of track 104. Although example ι〇〇 describes only one track 104 for simplicity and clarity, but storage The body may include a plurality of magnetic tracks 104. Each magnetic track 104 includes a plurality of grooves 106 and land 108. The land 108 is flat to reflect a thunder generated by a media player like a mirror The shooting point 110, so when the groove has a depth to generate a minimum intensity reflection reading, it can generate a maximum intensity reflection reading through a detector of the media player. The reference numeral 105 indicates that The transition of groove ι〇6 to land 10 8 and vice versa. Further referring to FIG. 1, the media player can move along the magnetic track 1 0 4 by a laser (not shown in the figure) by the media bone bean player. The laser point 11 is generated to obtain the intensity reflection as described by the intensity reflection read value waveform 112. iref is a peak value, where the peak value corresponds to the output of a photodiode (not shown) of the media player before high-pass filtering. Represents the maximum intensity reflection reading (ie, no photo-destructive cancellation) produced by a pure land 108 and the minimum intensity reflection reading (ie, photo-destructive) produced by a pure groove 106, respectively. cancel). In (also known as 114) 114 represents the difference between the maximum intensity reflection reading (i.e., It () p) and the minimum intensity reflection reading (i.e., Ibc) t). I3 116 describes the difference between the minimum intensity reflection high level 132 and the maximum intensity reflection low level 134 from a digital storage medium. Specifically, an upper limit level 122 of ι3 π6 indicates the minimum intensity reflection high level 132, while the low level 124 of 13 116 captures the high intensity reflection low level 134. In other words, 13 116 is the difference between the minimum intensity reflection high level 13 2 and the maximum intensity reflection low level i 3 4. The traditional media player requires 13 > 0.15 * ^ 1. ASY 120 describes 87819 -12- 200426783 A signal is not uniform, which indicates the difference between the center of Iu 114 and the center of I3 116. Note here that different media players have different laser energies, and the actual intensity reflection read value is different from It () p and IbQt described in the intensity reflection read value waveform 112 of each media player. . There are approximately 10 percent changes in laser energy at different media layers. Still referring further to FIG. 1, the media player can convert the intensity reflection read value waveform 112 into a binary data stream 118 (i.e., digital content). By using sampling along a groove 106, the media player can generate a series of binary bits 126 equal to zero in the relevant sampling section 103. Similarly, by using sampling along a land 108, the media player can generate a series of binary bits 128 equal to zero in the relevant sampling section. Note that the intensity reflection read value must be at least the high level 132 of the minimum intensity reflection read value of the media player in order to generate a representation of a portion of land 1 08 in the binary data stream 11 8 (ie, the bits are equal to zero) One bit. Similarly, the intensity reflection read value must be at least the lowest level of the media player's maximum reflection reflection value 13 4 to produce a bit in the binary data stream 118 representing a portion of the groove 106 (ie, equal to zero) ). As described in the intensity reflection read waveform 112 transition 105 between the groove 106 and the land ι08, when the intensity reflection read value transition between the groove and the land is changed, the media player can be in the binary data stream Convert the transition 105 into a binary bit 13 equal to 1. Figure 2 illustrates an example 2000 of a groove above or below the land 108 according to the present invention. The groove 106 has a laser point 110 which is narrower than the above-mentioned figure i. The degree (or depth) of the groove 106 is about a quarter of the wavelength of a laser digital storage medium that generates a laser point of 110, which can help to efficiently retrieve 87819-13-200426783 data from an optical storage medium. Note that when a laser enters a digital storage medium, the wavelength generated by the laser changes to λ / η, where λ is the wavelength in a vacuum and n is the refractive index of the digital storage medium. For example, for a specific wavelength of 780 nm for a laser and a refractive index of 1.58 for a polymer carbonate digital storage medium, the depth of the groove 106 is approximately 120 nm (ie, 780 / 1.58 / 4 = 120). The light 202 reflected from the recess 106 will destructively cancel the light 204 reflected from the land 108. Therefore, at the position shown in FIG. 2, the median player reads the intensity reflection reading obtained by the detector from the laser point 110 placed on the position (that is, to take). Decide. As mentioned above, because the laser energy of the media player changes, the sampled detector intensity reflection reading will change from the maximum intensity reflection reading ItQp, or the minimum intensity reflection reading Ibot. However, as mentioned above, the reading should completely exceed the minimum reflection intensity high level of the special media player 13 2, or completely lower than the maximum reflection intensity high level of the special media player, so the media player can determine a maximum or minimum intensity reflection Read the value. However, if the intensity reflection read is close to high level 132 or low level 134, it will cause a wobble (distortion from timing errors) in the binary data stream, or force the media player to arbitrarily assume a maximum intensity reflection read Value, or minimum intensity reflection read value. Figure 3 illustrates an example 300 of one or more fuzzy bits on a storage medium track in accordance with the present invention. According to this example, the distance modulation between two adjacent grooves can be used to generate one or more fuzzy bits. As described in FIG. 1 above, it is assumed that the laser point 110 is generated by a laser (not shown in the figure) of a special media player. As previously described in FIG. 1, the laser point 110 further describes the position used for sampling along the media magnet. It can be further assumed that a land is above or below the groove in Example 3 00 of the range 87819 -14- 200426783 in Figure 3. FIG. 3 depicts an intensity reflection read waveform 302 ′ which includes three intensity reflection read sections 312, 3 14 and 3 16 corresponding to the waveform 302 at positions (a), (b), and (c) respectively on a storage medium. . In addition, a minimum intensity reflection high level 322 and a maximum intensity reflection low level 324 are described in the waveform 302 of FIG. 3. A data stream 3 1 8 is further described in the example 300 of FIG. 3, which represents bits obtained from a plurality of samples. Note that only the relevant samples used at positions (a), (b) and (c) will be described in detail. As shown in position (a) of FIG. 3, the adjacent grooves 304 and the grooves 306 are adjacent to each other. The groove 304 and the groove 306 occupy about 50% of the surface area corresponding to the land lower or higher than the groove. When a sample is taken at position (a), the light reflected from the grooves 304 and 306 will destructively cancel the light reflected from the land. Therefore, the intensity reflection reading obtained through the detector of the special media player is a minimum intensity reflection reading 308. To be clear, with position (a), the intensity reflection read value of the waveform 302 part 3 and 12 shows that the intensity reflection read value obtained is completely lower than the maximum intensity reflection low level 324, and this can be used as binary data Stream 3 1 8 is converted to zero 326. As shown in position (c) of FIG. 3, adjacent grooves 304 and grooves 306 are not adjacent, and are around the laser point 110 (that is, the distance between the grooves 304 and 306 is (Approximately the diameter of the laser point). When the sample is taken at position (c), the intensity reflection reading obtained through the detector of the special media player is a maximum intensity reflection reading 310. Specifically, with position (c), the readings of the intensity reflections in the waveform 302 section 3 16 show that the light reflections that are mainly reflected from the land completely exceed the minimum intensity reflection high level 322. Therefore, the media broadcast 87619 -15- 200426783 zooming is to convert the intensity reflection reading to zero 328 in binary stream 3 18 at position (a). As described in position (b) of FIG. 3, adjacent The distance between the grooves 304 and 306 can be adjusted, so when the sampling is taken at position (b), the intensity reflection read value obtained through the detector of the media player is blurred The intensity reflection value is 309, that is, between the minimum intensity reflection reading value of 30.8 at the position (a) and the maximum intensity reflection reading value of 31 ° and the maximum intensity reflection reading value at the position (c). The median. The read value of the fuzzy intensity reflection 309 at the position (13) is between the maximum intensity reflection 324 of the waveform 302 and a minimum intensity reflection high level 322. The intensity reflection read portion 314 of the waveform 302 shows that the media player converts the blurred intensity reflection read value 309 to the fuzzy bits 330 and 332 (indicated by a question mark) on the conversion 320. Figure 4 illustrates another example bit of one or more fuzzy bits on a track of a storage medium according to the present invention. According to this example, the width modulation of a single groove 404 is used to generate one or more fuzzy bits. The direction of the length and width of the groove 400 is indicated by reference 412. As shown in the previous illustration of Fig. 3, it is assumed in Fig. 4 that the laser point 11 describes the position where the sample was taken along the magnetic track of the storage medium. It is further assumed that a land is above or below the groove 404 in the example 400 of FIG. FIG. 4 further describes an intensity reflection read value waveform 402, which includes an intensity reflection read value portion 414 corresponding to a position (heart, (... and Bu) on the storage medium. In addition, in the waveform 402 of FIG. 4 Describe a minimum intensity reflection south level 416 and a maximum intensity reflection low level 418. A data stream 422 is further described in FIG. 4 which represents-or more bits-obtained from a plurality of samples used. Note that only The correlation between the locations ⑷, ⑻, and 87887819 200426783 sampling will be described in detail. As described in position (a) of Fig. 4, the width of the groove 404 is about half the diameter of the laser point 110. When a sampling is at the location (a ) When acquired, the light reflected from the groove 404 destructively cancels the light reflected from the land above or below the groove 404. Therefore, the intensity reflection reading obtained through the detector of the special media player is A minimum intensity reflection read value 406 indicated by the intensity reflection read value portion 414 and the associated zero bit in the binary data stream 422. As described in position (c) of FIG. 4, the width of the groove 404 Is about zero. When a sample is When the position (c) is obtained, the intensity reflection read value obtained through the detector of the special media player is a maximum intensity reflection read value 4 丨 〇, and it is the intensity reflection read portion 414 and the binary data. The relevant zero bit representation of stream 422. This is because the reflected light at position (c) is mainly reflected from the land. As described at position ⑻ in FIG. 4, the width of the groove 404 is the groove 4 at position 〇. 4 The width is adjusted between the width of the groove 404 at position (c). Therefore, when the sample is taken at position (b), the intensity reflection reading obtained through the detector of the special media player is a blur The intensity reflection read value 408 is about the middle between the minimum intensity reflection read value at position (a) and the maximum intensity reflection read value at position. Specifically, it is related to position (13). The value of the intensity reflection of the waveform 302 is between the maximum intensity reflection low level 41 § and the minimum intensity reflection high level 416. As can be seen from the example 400 in Fig. 4, the width of the groove 40 is About half of the laser point 110 gradually changes to about zero, and there may be Change the intensity reflection read value to produce one or more fuzzy bits 424_ 428 ° Figure 5 疋 According to the present invention, one or more of the 89878 -17- 200426783 multiple fuzzy bits on a storage medium track is still described An example is shown in FIG. 500. According to this example, the depth adjustment of a single groove 504 can be used to generate one or more fuzzy bits. As shown in the first example of FIGS. 3 and 4, in FIG. 5, assuming a laser point 丨10. Describe the location where the sample took the magnetic track along a storage medium. Further assume that a land is above or below the groove 504 in the example 500 of FIG. 5. FIG. 5 further describes an intensity reflection read. The value waveform 502 includes intensity reflection values 514 corresponding to positions (a), (b), and (c) on the storage medium. In addition, a minimum intensity reflection chirp level 516 and a maximum intensity reflection low level 518 are described in the waveform 502 in FIG. 5. A data stream 522 representing one or more bits obtained from a plurality of obtained samples is further described. As mentioned above, only relevant samples obtained at positions (a), (1)) and (0) will be described in detail. FIG. 5 further describes a cross-sectional view 512 on the middle line of the groove 504, which describes the depth modulation of the groove 504. Referring back to FIG. 5 immediately, as specifically described in position (a), the depth of the groove 504 is about a quarter of the wavelength of a digital storage medium of a special media player. When a sample is taken at position (a), the light reflected from the groove 504 will destructively cancel the light reflected from the land above or below the groove 504. Therefore, the intensity reflection read value obtained by the detector of the special media player is a minimum intensity reflection read value 506, which is the correlation zero of the intensity reflection read value portion 5 14 and the binary data stream 522 Bit representation. Currently, as described at position (c), the depth of the groove 504 is approximately zero. When a sample is obtained at position (c), the value of the intensity reflection obtained through the detector of the special media player is a maximum intensity reflection reading value 5 1 〇, and the intensity reflection reading value portion 5 14 and the associated zero bit representation in the binary data stream 522. This is because the light reflected from the groove 504 at position (c) does not destructively cancel the reflected light from the land 87819 -18-200426783 ', thereby generating a maximum intensity reflection reading 5 10. As described in position (b) of FIG. 5, the depth of the groove 504 is adjusted between the depth of the groove 504 at the position (a) and the depth of the groove 504 at the position (c). Therefore, when the sample is acquired at bit i (b), the intensity reflection obtained through the detector of the special media player 1 is a fuzzy intensity reflection reading of 508, that is, approximately at the position (a ) Between the minimum intensity reflection reading and the maximum intensity reflection reading at position (c). More specifically, the intensity reflection reading portion 5 14 of the waveform 502 at position (1)) is between the maximum intensity reflection low level 5 1 8 and the minimum intensity reflection south level 516. It can be seen from the description of the cross-sectional view 512 of FIG. 5 that the depth of the groove 504 is gradually changed from about a quarter of the laser wavelength of the storage medium to about zero, and the intensity reflection reading can be effectively changed to produce One or more fuzzy bits 524-528. Fig. 6 is another example diagram 600 of one or more fuzzy bits on a storage medium track according to the present invention. According to this example, the reflectivity modulation of a metal layer 611 on land 604 can be used to generate one or more fuzzy bits. As in the previous example shown in Figures 3-5, in Figure 6, it is assumed that the laser point π 0 describes the position of the sample taken along a storage medium track. In this example, it is further assumed that samples are only taken on land 604. Figure 6 further describes the intensity reflection read value wave element 602, which includes the intensity reflection read value portion 614 corresponding to the positions (a), (b), and (c) on the storage medium. In addition, in waveform 602, it describes a minimum intensity reflection high level 616 and a maximum intensity reflection low level 618. A data stream 622 representing one or more bits obtained from a plurality of samples is further described. As mentioned above, only the relevant samples taken at positions (a), (b) and (c) will be described in detail. FIG. 6 further describes a waveform 612, which is described as a 87819-19-200426783 metal layer reflectance modulation on a land 604 that can be used to generate one or more fuzzy bits. Please refer to FIG. 6 again. As specifically described in the position (a), the reflectivity of the metal layer 611 is about 80 percent. Typically, the reflection from the metal layer 611 is uniform, that is, the metal layer can reflect approximately 80 percent of the light. According to FIG. 6, as described in the reflectance waveform 612, the reflectivity of the metal layer is adjusted between 80% and 10%. This is best achieved by modulating a high-intensity laser capable of scanning a predetermined land area and burning or cutting away the metal layer 611 corresponding to the land 604. More specifically, the burning causes the reflectivity of the metal layer 611 to decrease. Modulation of the reflection 611 from the metal layer at a predetermined location on the storage medium can be used to obtain one or more fuzzy bits. Therefore, at position (a), the reflectivity of the metal layer is at a low level of 10%. As a result, the intensity reflection read value obtained through the detector of the special media player is a minimum intensity reflection read value 606, and the intensity reflection read value portion 614 and the relevant zero position in the binary and the stream 622 Yuan said. At present, as described in the position (c), the reflectivity 611 of the metal layer is at a height of 80 percent. When a sample is obtained at position (c), the intensity reflection read value obtained through the detector of the special media player is a maximum intensity reflection read value 6 丨 〇, and the intensity reflection read value portion 614 The associated zero bit representation with the binary data stream 622. However, as described in position (b) of the reflectance waveform 612, the reflectance of the metal layer 611 is modulated between the reflectance at the position (c) and the reflectance at the position (a). Therefore, when the sampling is obtained at position (b), the intensity reflection reading obtained through the detector of the special media player is a fuzzy intensity reflection reading 608, that is, the minimum intensity at the position (... Between the reflection reading and the maximum intensity reflection reading at position (c). To be clear, at position sand) there is 87,619-20-200426783 off the intensity of the waveform 602. The reflection reading portion 614 is at the maximum intensity. The reflection low level 6! 8 and the minimum intensity reflection high level 616. It can be seen from the example 600 in FIG. 6 that the reflectivity of the metal layer is changed from about 80% to about 0%, and the intensity reflection reading from the land 604 can be effectively changed to produce one or Multiple fuzzy bits 624-628. FIG. 7 is a further exemplary diagram 700 describing one or more fuzzy bits on a storage medium track in accordance with the present invention. According to this example, the reflectivity modulation of a metal layer 611 in the groove 704 can be used to generate one or more fuzzy bits. As shown in the previous example of Fig. 6, in Fig. 7, it is assumed that the laser point 11 is a position describing the acquisition of a sample along a storage medium track. In this example, it is further assumed that the samples are taken in the groove 704. FIG. 7 further describes an intensity reflection read value waveform 702, which includes intensity reflection read value portions 714 corresponding to the positions (a), (b), and (c) of the storage medium. In addition, in waveform 702, it describes a minimum intensity reflection high level 716 and a maximum intensity reflection low level 718. Further described is a data stream 722 representing one or more bits obtained from a plurality of obtained samples. As mentioned previously, only the relevant samples taken at positions (a), (b) and (c) will be described in detail. FIG. 7 further describes a waveform 712 that describes the modulation of the reflectivity of the metal layer on the groove 704 that can be used to generate one or more fuzzy bits. With further reference to Fig. 7, as specifically described at position (a), the reflectance 611 of the metal layer is approximately 80%. The reflection from a metal layer 611 is typically consistent, i.e., the metal layer can reflect approximately 80 percent of light. According to FIG. 7, as described in the reflectance waveform 712, the reflectivity of the metal layer is adjusted between 80% and 10%. This is best achieved by adjusting the high-intensity lightning that is used to shoot a predetermined land area and burn or cut the metal layer 611 corresponding to the groove 704 to reach 87819 -21-200426783 to 611. More specifically, the firing can reduce the reflectivity of the metal layer 611. The modulation of the reflection from the metal layer 611 at the pre-footed position of the storage medium can be used to learn one or more fuzzy bits. Therefore, at position (a), the reflectivity of the metal layer is in percent < 80 height. As a result, the intensity reflection reading obtained through the detector of the special media player is a minimum intensity reflection reading of 706, and the correlation between the intensity reflection reading portion 714 and the binary data stream 722 is Zero 7G table 7F. Note that the reflectivity of the metal layer on the groove is proportional to the intensity reflection reading obtained through the media player. Specifically, when an intensity reflection from a groove represents a minimum intensity (that is, approximately 0 percent), reflections from land (above or below the groove) have no destructive interference, so from the groove The intensity reflection read value of the position is about the middle between the maximum intensity reflection read value low level 7 丨 8 and the minimum intensity reflection high level 716 on the waveform 702. However, when the intensity of the reflection from the groove is a maximum intensity (i.e., about 80 percent), the reflected light from the groove is destructive to cancel the reflected light from the land. The consequence of this is that the reflection intensity is a minimum intensity reflection. Still referring further to FIG. 7, at position (b), the reflectance of the metal layer 611 in the waveform 712 is gradually adjusted to less than a typical 80%. As a result, the intensity reflection readings obtained through the special media player ❹] f | will increase inversely, but still remain at a minimum intensity reflection reading of 708, such as the intensity reflection reading portion 714. Representation with associated zero bits in binary data stream 722. However, at position (c), the reflectivity of the metal layer 6 is adjusted to a low level of ten percent. When a sample is taken at position (c), the intensity reflection read value obtained by the detector of the special media player is a fuzzy intensity inversion 87919 -22- 200426783, and the reading value is 710, and the intensity reflection reading is 710. The value portion 714 and the relevant fuzzy bits 7 2 4 _ 7 2 8 in the binary data stream 7 2 2 are represented. The blurred intensity reflection read value of 71 0 is intermediate between the minimum intensity reflection read value at the position (a) and the maximum intensity reflection read value at the position (b). More specifically, the intensity reflection read portion 714 of the waveform 702 at position (c) is between the maximum intensity reflection low level 7118 and the minimum intensity reflection high level 716 (ie, at about the midpoint 717) . It can be seen from the example 700 of FIG. 7 that the reflectivity of the metal layer 611 is changed from about 80 percent to about 10 percent, and the intensity reflection reading from the groove 704 can be effectively changed in inverse proportion to One or more fuzzy bits 724-728 are generated. Please refer to Figure 3-7. As mentioned earlier, the laser intensity from different media players will vary by about 10%. Similarly, the minimum intensity reflection high level and the maximum intensity reflection low level of each player may be different. To account for the difference in laser intensity and media player ㈣—or multiple fuzzy bits, multiple fuzzy bits can be provided as follows. The distance adjustment between the groove groove and the groove in Fig. 3 is N. Bismuth can be provided with a plurality of groove pairs for each continuous groove pair, and each continuous groove pair has a larger groove distance adjustment. For example, the groove 30 is planted 3: the diameter of the pair having the distance between the relevant grooves changed from about zero to about the laser field size 110. In the case where the width of the groove 400 is adjusted in FIG. 4, the width of the groove 404 is changed from about half of the vertical position of the groove to approximately zero. The depth of groove 5 04 in Fig. 5 is adjusted) The main, 3, and brother 'ice degrees are changed from about a quarter of the laser wavelength in the storage medium to about zero. In the case of the reflectivity of the metal layer in FIGS. 6 and 7, the reflectance of the metal layer 61! Is changed to about 80% by about 10% (and vice versa). The agency 1 takes the high level of low intensity reflection and 87619 -23- 200426783. The low level of maximum intensity reflection is used for a special media player. It will always be the position of the intensity reflection. The read value is fuzzy (ie, fuzzy bit). . In addition, the configuration of the additional fuzzy bits (ie, the same distance modulation, width modulation, depth modulation, or metal layer reflectance modulation fuzzy bits) of the same word characteristics along redundant storage media tracks is better. In addition, different combinations of the preceding fuzzy bits may be configured along one or more tracks of a redundant storage medium. FIG. 8 is a storage medium 800 (e.g., an optical storage medium) according to the present invention. The storage medium 800 includes a lead-in area 802 that includes a digital mute (or zero data) on the main channel plus a directory on the subcode Q channel. The lead-in area allows the laser of the media player to follow the land and groove, and is synchronized with the digital content in the program area 806. The digital content in the program area 806 includes data, which can be audio, video, or computer data that is typically interleaved across multiple tracks. The lead-out area 804 includes a digital mute (or zero data) to define the end of the program area 806. According to FIG. 8, the storage medium 800 further includes an authentication program 808 configured in the lead-in area 802 or the program area 806 to authenticate the storage medium 800, thereby providing copy protection if the storage medium is not exactly as described in FIGS. 10 and 11 below. . With particular reference to the authentication program 808 in Fig. 8, when the authentication program 808 is stored in the lead-in area 802, the media player will automatically read the lead-in area 802, so that the authentication program 808 can be automatically loaded and executed. If the authentication program 808 is arranged in a position in the program area 806, when the media player reads this position, the authentication program will be automatically loaded and executed by the media player. In addition, the authentication program 808 can be combined with an installer to install the digital content stored on the digital storage medium 800 on a personal computer (ie, "PC"), such as 87619 -24- 200426783, such as the setup of the WindowsTM environment. exe file. Therefore, at the time of installation, the authentication program 808 can be executed. Further describing FIG. 8, according to the present invention, the storage medium 800 further includes (if indeed) one or more fuzzy bits arranged at predetermined positions 8 10 of one or more predetermined tracks of the storage medium 800. As described in the enlarged portion 812, one of the predetermined positions 810 containing one or more blurry bits is 10 mm in size. Conventionally, the enlarged portion 812 is described in accordance with the present invention with one or more fuzzy bits (ie, distance modulation, width modulation, depth modulation, and metal layer reflectance modulation) obtained through various techniques. ). The digital content stored on the storage medium 800 is protected in such a way that the authentication program 808 is not executed and the media player cannot read the digital content (or a part thereof). If the authentication program 808 cannot find one or more fuzzy bits το at the predetermined position 810 of the storage medium 800, the media player will stop playing the digital storage medium 800, thereby denying the user access to the storage medium Stored digital content 800. In addition, if the authentication program 808 is combined with an installation program, the installation program can determine whether the authentication program 808 cannot be found on the storage medium 800 (predetermined location 8H)-or multiple fuzzy bits , Thereby denying users access to the digital content stored on the storage medium 800. Figure 9: A media player used to execute the authentication procedure 808 according to the present invention (that is, to determine whether or not the fuzzy bits are shouldered to a predetermined position of the storage media outline) < State 900 (e.g., optical media device) 800. The media player 900 is preferably a traditional optical media player that does not require additional hardware. However, the present invention allows the present + poor Ming is not limited to the similar media # other media players can be easily implemented based on the following in Ming II a 87819 -25- 200426783 900. The media player 900 includes a motor 900 for rotating the storage medium 800 times. The electronic control and data acquisition circuit 914 can control the speed of the motor 902 and the position of the laser 910 on the storage medium 800. The incident light generated through the laser 91 is transmitted to the quarter-wave plate 907 through a beam splitter 908 to rotate the polarization of the incident laser light by 45 degrees. The objective lens 906 focuses the incident laser light on the storage medium 800. The storage medium 800 can reflect the incident laser light, and the objective lens 906 can collect the reflected light of the quarter-wave plate 907 to further rotate the polarization of the reflected light by 45 degrees. Because the polarization of the reflected light has been rotated by 90 degrees, the beam splitter can reflect the reflected light to the detector 912. The detector 912 can be said to take the reflected light intensity from the storage medium and transmit the signal to the electronic circuit 914. The electronic control and data acquisition circuit 914 can decode the signal and transfer it to the memory 918. The microprocessor 916 can control the electronic control and data acquisition circuit 914. FIG. 10 is an exemplary flowchart 1000 for authenticating a storage medium according to the present invention. Assume that the storage medium has been inserted into a media player, such as a media player 900 that can read the storage medium. It is further assumed that the user attempts to use a media player to read the storage medium. Please refer to the flowchart. At step 1002, the media player loads the authentication program 808 into the memory 918, and the microprocessor 916 executes the authentication program 808, which includes the following step 100. 4_ 1022. In step 1004, the player reads a predetermined position 810 on the storage medium 800 to obtain the bits in the binary data stream. In step 1006, the read result of the predetermined position is stored in the memory 918. In step 1008, it can be judged whether the predetermined position is read different times. If the predetermined position is to be read many times, the 'predetermined position will be read again at step 104. Otherwise, if 87819 -26-200426783 is not re-read at the predetermined position, flowchart 1000 will continue at step 1010. Preferably, the predetermined position is read at least twice. At step 1010, the results of different reads from the predetermined position 8 10 are compared with each other. With further reference to FIG. 10, in step 1012, it can be determined whether the result of reading different times changes with different readings. If the result is substantially the same for every 1 purchase, or an error message is generated for each read, the authentication program 808 will not authenticate the storage medium 800 at step 104. Therefore, in step 1016, the authentication program 808 can stop the electronic control and data acquisition circuit 914 from rotating the storage medium 800 (that is, stop the storage medium from reading by the media player). However, in step 10-12, if it is judged that each read result is arbitrarily changed with different reads, the flowchart will continue at step 丨 〇 丨 8. It is assumed here that the change in the result of different readings indicates a possible fuzzy bit 'at a predetermined position, that is, indicates a possible authentication. In step 丨 〇 丨 8, it is further judged whether it is necessary to determine a possible authentication of the storage medium 800. The authentication program 008 can be set the number of repetitions in advance to determine whether the storage medium 8000 is accurate. In step 1018, if the judgment result needs to be confirmed, the flowchart 1000 repeats to step 1004 to read another predetermined position on the storage medium 800. However, if the judgment does not require further confirmation, the storage medium may be authenticated at step 〇20. At step 1022, the player continuously loads data into the program area 806 of the data medium 800 in a conventional manner. FIG. 11 is a mud map 1100 describing another example for authenticating a storage medium according to the present invention. It is also assumed that the storage media is plugged into a media player, such as a media player 900 that can grab the storage media. It is further assumed that the user uses a media player to read the storage medium. Please refer to the flowchart 87819 -27- 200426783 1100. In step 1102, the media player inserts the authentication program 808 into the memory 918, and the microprocessor 916 can execute the authentication program 808, which includes the following steps 1104-1122. At step 1104, the media player can read the data string at a predetermined position 810 of the storage medium 800. Note that the data string contains one or more fuzzy bits and non-fuzzy bits. In step 1106, the result (ie, a series of materials) is stored in the memory 918. In step 1108, it can be judged whether or not the predetermined position is read many times. If the position is to be read many times, the flow chart 1100 will continue at step 1104. Otherwise, if it is judged that the predetermined position is not taken many times, the flow chart 1100 will continue at step 1110. It is best to read the preview position at least twice. Thereafter, it is judged whether or not the crumb is taken at another predetermined position 810 on the storage medium 800 at step 1010. Steps no # and 1108 may be repeated at all subsequent predetermined positions to be read. However, if there are no other predetermined positions to be read, in step 1112, it can be determined whether the data string read at each predetermined position has fuzzy bits. That is, the same bit in all read data strings at each pre-position can be compared to determine whether there is a fuzzy bit presentation (that is, whether the same bit arbitrarily changes with different data strings in the predetermined position ). If it is judged in step 骡 12 that no fuzzy bit exists, in step 1114, the storage medium will not be authenticated. Then in step 1U6, the authentication program 808 instructs the electronic control and data acquisition circuit 914 to stop the textile storage medium. However, in step 1112, if there is a fuzzy bit in the data string, in step 1118, the position of the fuzzy bit in the data string can be confirmed by the authentication program 808. At step 112, the storage medium may be authenticated. At step 1122, the media player can continuously load data into the program area 806 of the storage medium 800 in a conventional manner. 87819 -28- 200426783 FIG. 12 is a first example flowchart 1200 for creating a storage medium containing one or more fuzzy bits according to the present invention. At step 1202, the digital content (including the authentication program) recorded on the storage medium may be converted into a format for a storage medium type, such as optical, magneto-optical, or mixed media. At step 1204 'the one or more fuzzy bits are added in a predetermined available space in a format. One or more fuzzy bits can be added by any of the following modulation techniques: modulating the distance between two grooves; adjusting the width of a groove; and adjusting the depth of a groove. Single-layer lithography can be easily implemented to achieve distance and width adjustment, while multi-layer lithography can be easily implemented to achieve depth adjustment. In step 1206, the redundant bits in the format can be adjusted as described below to generate an increased fuzzy bit in the format via the error correction device of the player. The format is used in step 1208 to create a mask. In step 1210, a master system is established using a mask. Finally, at step 1212, a plurality of storage media are recorded using the master. Alternatively, each of the plurality of storage media may include a combination of a digital valley, an authentication program, and a fuzzy bit. FIG. 13 is a second example flowchart 1300 for creating a storage medium containing one or more fuzzy bits according to the present invention. In step 1302, one or more fuzzy bits are added to the available space in a format for the type of storage medium, such as optical, magneto-optical, or mixed media. As described in FIG. 12 above,-or multiple fuzzy bits can also be increased by any of the following modulation techniques: modulating the distance between two grooves; _ changing the groove width; and adjusting the groove

depth. Furthermore, the single-layer lithography can be delivered and the A 1 W J can easily implement distance and width adjustments, and the multi-layer lithography can easily adjust the distance and width. In step 1 3 0 4 ′, the redundant bits in the format may be rounded up to generate an increased fuzzy bit in a non-correctable format through a player's error 87819 -29- 200426783 error correction device. In step 1306, the format is used to create a mask. A master system is established in step 1308 using a mask. At step 1310, the digital content (including the authentication program) recorded on the storage medium is converted into a format for the storage medium type. At step 1312, the formatted digital content is written to the parent via a laser or other comparable writing device. Finally, in steps 13 to 14, a plurality of storage media can be cut for distribution by using the master. FIG. 14 is a third exemplary flowchart 1400 for establishing a storage medium including one or more fuzzy bits according to the present invention. In step 142, the digital content (including authentication programs) recorded on the storage medium is converted into a format for the storage medium type, such as optical, magneto-optical, or mixed media. In step 1404, the format is used to create a recessed mask in the open space for positioning one or more predetermined positions. A parent is created in step 1406 using a mask. At step 1408, a storage medium is cut using a master. Note that a plurality of storage media may be cut using a matrix. In step 1410, the intensity of a laser is adjustable to reduce the reflectivity of the metal layer of the storage medium at a predetermined position to generate one or more fuzzy bits. Specifically, the laser intensity can be adjusted to partially remove the predetermined position of the reflective metal layer, thereby establishing a position that reduces the reflectivity (ie, one or more fuzzy bits). Finally, in step 1412, the laser is used to adjust the redundant bits corresponding to the predetermined position where the fuzzy bits are added, so as to generate non-modifiable fuzzy bits through the error correction device of a player. That is, referring to Figure 12-14, the redundant bits (in the form of error correction symbols) are adjusted during or after the formatting of the storage medium, so that the media playback error correction device of the 78719 -30- 200426783 device is in the media player. It is not possible to correct one or more fuzzy bits arranged along the -or multiple tracks of the misstored media. Traditionally, when a media player reads a storage medium, redundant bits can be used by the media player to determine whether they correspond to other digital content embedded in the storage medium in such a way that they can not only determine errors. Whether it happened, and whether the error can be corrected in some cases. A fixed number of redundant bits can be reduced to form a data structure known as an error correction codeword (that is, "ecc "). When reading from a storage medium, such as 1 a media player encounters less than " 3T " (there are two consecutive values in the binary data stream bit) or two transition channel sequences exceeding " 11T " (the two-bit value separated by a value of more than 10 bit 0, two, media The player will flag the bit as invalid, and mark the invalid bit as "Erase". In the decoding and reordering commands, media players using ECC will automatically correct the "Erase", Invalid bits. ECC can only be used to correct a limited number of errors. That is, the media player can detect whether errors exceed a limited possibility, but the media player cannot correct them. In addition, when the number of errors in ECC The probability of detecting errors will decrease when you increase it. One way to adjust the redundant bits with reference to the figure is to abandon or invalidate the automatic correction of ECC. This is best done by adjusting the redundancy in the ecc pattern. Bitwise Achieved, it will cause the ECC error to exceed the relevant limit. In addition, if the pattern is created on specially selected ECCs, where the selected ECCs correspond to one or more fuzzy bits configured on the storage medium, the media player will Can't fix special ECC-or multiple fuzzy bits' but will pass uncorrected one or more fuzzy bits. Therefore, the redundant 87619 -31- 200426783 bit 7G adjustment can be corrected by the media player's error The device generates one or more non-modifiable fuzzy bits./ Although the present invention specifically shows and describes the preferred embodiment, those skilled in the art will understand that previous and other changes in form and detail can be achieved without departing from The spirit and scope of the present invention.
